Application filed May 21,

lhis invention relates to a machine that has been devised for use in theshelling of green peas and it comprises a construction that allows forthe pea pods being fed in between mangio-like rollers so that they burstand free the peas which fall on the front side of such rollers, whilethe pods or` shells are carried through by the rollers and delivered onthe rear side thereof.

The machine designed is illustrated in the accompanying drawings, inwhich z- Figure l. is a side elevation, and

Figure 2 a front elevation thereof.

.liignre 3 is a sectional side elevation, and

Figure i a sectional front elevation.

The machine, as designed, comprises a base A of approved nature such asto adapt the machine for stable support upon any table or other surface,and if necessary, for clamping to such surface. Upon the base is fixed apair of side frames B#B disposed to extend vertically at the necessarydistance apart and covered in at the top by a cover plate C so asthereby to constitute the housing framework of the appliance, open atthe front and back.

Fitted into the space between the side frames B are two rollers D'Ddisposed in parallel lines one above the other. Each of these is fixedupon a spindle E that passes out at each end through a vertical bearingslot F formed in that side of the frame. The spindle E of the lowerroller D rests in the bottoms of the slots F on both sides so that it issupported to rotate therein. The upper roller D then rests with itsperiphery upon that of the lower` roller and its spindle eX tendsloosely through the slots F so that while being free to rotate, it mayalso rise to an extent limited by the length of the slots, which lengthis substantially greater than the distance between the axes Vof theprojecting spindle ends. The two rollers are kept normally in contact bythe weight of the upper. roller resting on the lower.

The lower spindle E, at one end, has a 1anlr handle G fixed thereon toprovide for ts turning and the two spindles are geared together by thegear wheels H So that by the rotation of the lower roller, both rollerswill be positively driven, mangle fashion.

A feeding tray J is provided and shaped to extend in between the sideframes B to a position close up to the point of contact between therollers D-D- This tray is sup- 1923. Serial No. 640,540.

ported at its inner end upon Va long pin K that passes through andacross between the side frames and through wings on the tray. This pinis capable of being withdrawn so that the tray may be removed when themachine is not in use. rllhe outer end of the tray may be continued forany desired distance to provide for a supply of pea pods being spreadthereon, such outer end being then supported by any available means.

M is a chute or inclined table fixed between the frame members B toextend from beneath the lower roller D towards the front of the machine.N is a similar chute, or

inclined table, fixed to extend from beneath the roller D, to the rearof the machine.

The rollers D and D are made of rubber or lilre wear resisting andresilient material. In the operation of the machine therefore, the peapods are fed down the tray J by one hand of the operator, while therollers are turned by the other hand. The pods are fed, end on, betweenthe two rollers so that they are gripped by the rollers and drawn in.|This pressure of the rollers on the pods causes them to splitlengthwise along theirV seams thereby freeing the peas which fall on tothe table M and run down it into any receptacle placed beneath. Theshells are then carried through and fall on the rear tray N andgravitat-e down it into the requie site receptacle.

The manner of mounting the rollers, as described, will allow of theupper roller lifting to compensate for any extra feed between therollers. At the same time the weight of this upper roller will besufficient to cause the frictional grip required to feed the podsthrough.

Vile claim l. A small, portable pea. shelling machine, comprising aframe consisting of a base plate adapted to rest on a table or othersupport, two vertical side cheeks fixe-d at their lower ends thereto inspaced, parallel relation, and a cover plate extending across the upperends of the cheeks and fixed to the same; coacting shelling rollersmounted in the space between said cheeks; an inclined feed trayextending into the frame between said cheeks and connected therewith,said tray terminating at its lower end adjacent said rollers; aninclined discharge chute for the shelled peas fixed between the cheeksto extend forwardly and downwardly from beneath the rollers; f indiaseparare inclined discharge elinte for the Shells lined betweensaidelieelis to extendfdownwardly andiearwardly .from beneath saidrollers.

2. A small, portable pea shelling machine, according to claim l, inwhich the inclined feed tray .is provided with perforated Wings at irslower end, tliroughmT rielrnndi through registering perforatons in thecheeks a long supportngfpn is removably inserted, tlierel0 by to enablethe Withdrawal of said pin and alle` removal of the tray when jdiemachine is not' in use.

In testimony whereof, We aix our Signatures.
